Missing Mobile Viewport Tag: How to Fix It
The viewport meta tag tells phones to render the page at the device width instead of a zoomed-out desktop layout.
Quick fix: Add <meta name="viewport" content="width=device-width, initial-scale=1"> so the page displays correctly on phones. Google indexes the mobile version first.
Why it matters for SEO
Google indexes the mobile version of your site first. Without a viewport tag, the page is not mobile-friendly, which hurts rankings and makes text tiny on phones.
How to fix it
- 1Add the viewport tag inside <head>.
- 2Use width=device-width and initial-scale=1.
- 3Do not disable zooming with user-scalable=no, as it hurts accessibility.
- 4Test the page on a real phone after the change.
